Hi guys, I have a base form in one BPF after I fill this info I hit Saved and the business process flow starts.

Lets name this process, Process 1, this process is inside one entity named opportunity.
Inside this entity, I have made a second BPF named Proccess 2, even though it's a new process, it still have the same base form.
Is there a way to change the based form and to change the fields inside?
I need to fill a different info but still in the same entity.
Thanks
